S32K148 SAI - clock edge to data out

Hello,

In my application I am using S32K148's SAI0 as transmitter and bitclock and framesync slave. I noticed that there is about 15-20ns delay between the external bit clock edge and data being output (please see attached screenshots). Can this be descreased by some register configuration?

Best regards,

Jakub

Hi Jakub,

The delay is specified in the datasheet rev.11 and it seems to be within the specification.

I would recommend measuring the analog signal with an oscilloscope.
